Well since I bought my 2001 Mazda B3000 3.0L I have noticed that when I start the truck it shakes and the idle bounces. Not really bad, maybe up and down 200rpms but it is there and annoying. Also it only does this while cold. I have cleaned the IAC, put a custom CAI with a K&N on, cleaned Tb, and seafoamed it. My truck only has 35,000miles on it so it should not need a tune up.
Also if yall could tell me what these 3.0L's idle at? Mine is 1200 at cold and 900-1000 warm. Thanks!

Oh ya I forgot to say I have cleaned the MAF 3 times. And the reason I put the CAI and K&N in is because of this problem. This happened before when it was stock.
Also to make it more clear I still have the box I just put 3in. tubing from the box to the wheelwell and 3in tubing from the box to tb. Also snorkel is out.
